ALEXANDER FARCHAR GRAY, OF BELLEVILLE, ILLINOIS.

i M PROVEIVI ENT lN WATER- ELEVATO-R'S.

Specilication forming part of Letters Patent No. 34,629, dated March 11,1862.

To all whom it may concern:

Be it known that I, ALEXANDER FARCHAR GRAY, of Belleville, in the countyof St. Clair, in the State of Illinois, have invented a new and usefulMachine to be used in Drawing Water from Wells and .Oisterns5 and I dohereby declare that the following is 'a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawing, makinga part of this specification, inwhich the iigure is a perspective view.

A is a cylinder or roller; B b b, arms of recoiling-plate; O,ratchet-wheel; D, gudgeon; E, brake ;':F, socket; G, click; H, ilatchain; I,

link cast in connection with a cup open at the bottom; J, bail; K lo,curved ears attached to the mouth of the bucket; L, tilting-rod; M,projecting plate for the attachment of the tilting-rod; m, pointsshowing the position of the right-hand plate; N, metallic plate'covering the upper edge of the inside wall of the trough; O, bottom ofthe trough forming an' inclined plane to the corner P; Q, bucket.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

I construct my well-box in the form shown in the accompanying drawings,using the scale whichaccompanies them as a guide for the properconstruction of its several parts. Before I put the box together I screwpermanently to each end of the cylinder the recoiling-plate (which isprovided with lfour arms, three of which are seen at B bb, projectingbeyond the circumference of the cylinder A) and the ratchet-wheel C,both being cast in metal.

A means the drilling of a hole through the brake and the attachment bymeans of a bolt and nutare dispensed with. The click Iattach in theusual way, as seen at G, The flat chain H is constructed by havingsquare links cast in malleable iron and then looped together withhoop-iron and riveted in the center. The link I, which is designed forthe attachment of the rope7 is also cast in malleable iron, with theaddition of acup open at the bottomlarge enough to admit the passage ofthe end of the rope, which is then knotted and drawn back tight into thecup, forming a swivel, the metal cup protecting the knot from wear. Thebail J, I form so that it can be connected with the chain in the samemanner as the links. Either one of the curved earsK k, which areattached to the mouth of the bucket Q, is sure to catch on thetilting-rod L, as the flat chain H will not permit any other side of thebucket to be presented than the two sides which are furnished with thecurved ears, when the bail J is attached to the bucket on the contrarysides. The tilting-rod L, I make out of round wrought-iron of suitablesize, extending the full breadth of the well-box, and bent in the manneras seen in the drawing, slipping its bent ends into the holes of theprojecting plates, as seen at M m. The tilting-rod, bent and attached inthis manner, draws the bucket forward, emptying its contents as soon aseither of the curved ears K la come in contact with it, which is sure totake place when the bucket is raised by turning the windlass, and itwould be well enough to remark that the point of tilting by thisarrangement is not confined to any particular spot on the tilting-rod.

- I attach, by means of common screws, to the upper edge of the insidewall of the trough a metallic plate, as seen at N, broad enough toproject over the wall about onequarter of an inch, which prevents anyrush of water from the trough back into the well.

The bottom of the trough o, I construct in such manner as to form aninclined plane, its lowest point being at the outer corner P, where ametallic spout is attached, which can be seen by referring to thedrawing.

I use in the construction of the bucket Q a flat metallic bottomsupplied with a common leather valve capped with metal.

As the form and relative size of the wellbox are indispensable to theproper Working of my machine, I have furnished a scale as a guide forits proper construction, which can be seen by referring to the drawing.

I am well aware that buckets have been provided With ears or hooks forthe purpose of tilting them. This I do not claim; but

I claim-m 1. The combination and arrangement of the cylinder A, With therecoiling-plate and arms B b b, ratchet-Wheel and gudgeon G, the fiatchain H, the inode of fastening the rope at I, the Vform of the bail Jfor the attachment of the chain H, the peculiar shape of the ears orhooks K k, adapted to the tilting-rod L, and the shape of thetilting-rod and its mode of attachment at M on;

2. The plate N on the upper edge oi' the inside Wall of the trough, incombination with
